Quiz One Review Flashcards
What do non metals and metals create
Solid compounds
What state in pure form are only solids
Metals
What is a metal that in pure form is not solid
Mercury
What do non metals and non metals create
All three states
What group is not found in nature in combined form
Noble gases
Ionic
Metals and non metals
What is needed to change states
Energy to break bonds
Octet
When valence shell is full-
What does the atomic number show
How many electrons
Bohr model
Shows all shells 2,8,8
How are charges created
By unbalence in protons and electrons
Octet rule
Atoms gain/ loose to fill valence shells
What can show valence electrons
Groups, end of the number
Electron dot diagrams
Show valence electrons
Work clockwise when drawing dots
Bonding electrons
Singular electron
Lone pairs
Paired electrons
Ionic bonds
Metals and non metals
Metals lose electrons to follow octet rule
What should be remembered when drawing ionic bonds
Square brackets for ions
Cattion
Postive
Anion
Negative
What needs to be reduced
If the number of the amound of the element is possible when combined
Covalent bonds
Share electrons
Non metals
Molecular compounds
Are compounds where atoms are bonded
Process for drawing out covalent bonds
Valence electrons and see which have the most bonding electrons and it will be the center
Distribute atoms around pherphiral after doing center and make sure they all have octets
What indicates and acid
H
What are two exceptions to the octet rule
Boron has three valence and will be filled by 6
Berylium has two valence and will be filled by 4
Structural formula
Just show the lines for bonds
